  When decoding a 10bits bitstreams HEVC driver should only expose
10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
when bit depth change and to correctly set match_depth in pixel formats
enumeration.

Fixes: dc39473d0340 ("media: hantro: imx8m: Enable 10bit decoding")

Should be:

case V4L2_CID_STATELESS_HEVC_SPS: {

...

Same for VP9.

Thanks,
